SZ-TC01 Truck Crane LMI
Product Overview
The SeeZol SZ-TC01 Load Moment Indicator (LMI) is an essential safety component specially developed for truck cranes. It continuously monitors the crane’s real-time load, working radius, and boom status to effectively prevent equipment overload and overturning accidents. By collecting and analyzing mechanical operating data together with the equipment’s technical parameters, the system delivers timely and accurate visual and audible safety warnings throughout the lifting process—safeguarding on-site operational safety and compliance.
The SZ-TC01 fits truck-mounted and all-terrain cranes working from traveled positions, where overload and tipping are the dominant risks, and supports safer lifts in construction, petrochemical, and general lifting projects.
Applicable Models
Truck cranes and all-terrain cranes (refer to rated capacity chart per model).
